When do I need to waterproof a bath?

A bath on its own - used only as a bath does not need to be waterproofed. However, if you have an over-head shower above the bath then we would recommend that you consider as how best to waterproof the installation. If you are finishing with wall panels, we would recommend that you use Classi Seal. If on the other hand you are tiling, then you have two options- Classi Plus which will waterproof between the ledge of the bath and the wall or the Classi Kit which waterpoofs this ledge as well as the walls.


How to use Classi Plus

Step 1

Thoroughly roughen and clean the sides of the tray or bath that the Classi Plus is to be attached.

Step 1

Step 2

Remove the backing paper 100mm at a time and align the top of the adhesive strip with the top edge of the shower tray or bath and firmly press on by hand.

Step 3

Before applying around the corners, pinch the Classi Plus to allow extra material in the corners ā€“ this helps with subsequent tiling. When finished applying, give the Classi Plus one last rub all the way around to ensure the perfect seal ā€“ paying special attention to the corners.

Step 4

Apply C2 tile adhesive to wall behind Classi Plus upstand. Press upstand into adhesive with the back of the trowel ensuring there are no air pockets.

Following tiling or wall panelling, finish with a Neutral Cure Sanitary Grade 100% Silicone. Classi Plus prevents water leakage from around shower trays and baths caused by the inevitable shrinkage and movement within buildings.
